Key Characteristics and Capabilities:
-
Guidance System: This is the core of the WS-35. It uses a combination of guidance methods:
-
GPS/INS (Global Positioning System/Inertial Navigation System): This is the primary guidance, allowing it to navigate to pre-programmed coordinates. It almost certainly uses China’s BeiDou satellite navigation system for enhanced accuracy and independence from foreign GPS signals.
-
Semi-Active Laser (SAL) Seeker (likely): It is strongly believed to have a terminal laser seeker option. This would allow a forward observer or drone to “paint” a target, enabling the shell to adjust its flight in the terminal phase to hit moving targets or for increased precision against specific points.
-
-
Warhead: It carries a high-explosive (HE) warhead. The key is that its precision allows it to achieve the same destructive effect as many unguided shells with a single round, drastically reducing the number of shells needed to destroy a target.
-
Range Extension: The WS-35 achieves its extreme range through two key features:
-
Base Bleed (BB): A small pyrotechnic charge in the base of the shell reduces base drag by filling the low-pressure area behind the shell as it flies.
-
Glide Capability: It features pop-out canard fins and likely larger tail controls. After the ballistic phase, these fins deploy, allowing the shell to glide and maneuver over long distances, correcting its flight path to the target.
-
-
Launch Platform: It is fired from standard 155mm howitzers, such as the PLZ-05/05A and PLZ-52 self-propelled howitzers, which are the mainstay of the PLA’s heavy artillery units.

-
vs. the M982 Excalibur: The WS-35’s most striking feature is its claimed range of approximately 100 kilometers, which is more than double that of the Excalibur. This suggests a greater emphasis on glide performance. The Excalibur is renowned for its exceptional accuracy (CEP of ~2m).
-
vs. the Krasnopol: The Russian Krasnopol is a capable but older system that is purely laser-guided. This means it requires a forward observer to maintain a laser lock on the target until impact, making it weather-dependent and risky. The WS-35’s GPS/INS guidance allows it to operate all-weather and without a forward observer for fixed targets.
-
vs. Standard Shells: This is a night-and-day difference. The WS-35 is a single-shot, single-target weapon. A standard artillery barrage requires firing dozens, if not hundreds, of unguided shells to have a high probability of hitting a point target, expending vast amounts of ammunition and time.
Strategic Significance:
The WS-35 is a potential game-changer for several reasons:
-
Revolutionizes Counter-Battery Warfare: It allows Chinese artillery to outrange almost all existing NATO and allied artillery systems. A PLZ-05 equipped with WS-35 shells could theoretically engage and destroy enemy artillery batteries from a safe distance without them being able to fire back.
-
Creates a “Poor Man’s Air Force”: It provides ground commanders with a rapid, all-weather, precision-strike capability against high-value targets (e.g., command posts, radar sites, vehicle concentrations) that might otherwise require calling in an airstrike or using a short-range ballistic missile.
-
Enables Network-Centric Warfare: The shell is designed to be fed target data from drones, satellites, and forward observers, integrating artillery into a digital battlefield network for rapid target engagement.
-
Reduces Logistical Burden: While each guided shell is expensive, the fact that one shell can destroy a target that previously required 100+ unguided shells dramatically reduces the overall logistical burden for ammunition transportation and storage.
Challenges: The main challenges for a system like the WS-35 are its high cost per unit and the complexity of integrating the necessary digital fire control networks to fully utilize its capabilities.
In summary, the WS-35 is a long-range, precision-guided 155mm artillery projectile. If its claimed performance is realized, it represents a significant advancement in artillery technology, potentially altering the tactical calculus in modern land warfare by giving Chinese forces a decisive range and precision advantage in the artillery domain.
